Embodiment Construction

[0043]figure 1 A first embodiment of a connection device 1 of structural elements, in particular a first structural element 2 and a second structural element 3 , according to the invention is illustrated. The device 1 comprises a housing 4 defining a cavity 14, preferably of frusto-conical shape, associated with a plate 6 fixed to the first structural element, for example by welding 2. exist figure 1 In the preferred embodiment, the structural element 2 is tubular and has a circular, square or rectangular cross-section. The plate 6 is fixed to the tubular structural element 2 such that the housing 4 extends inside said tubular structural element 2 . Preferably, the hinge portion 6a is also associated with the plate 6 . The side wall 10 of the housing 4 has one or more holes 12, preferably four holes.

[0044] figure 1 The connecting device 1 further comprises a connecting body 5 having an insertion portion 119 preferably having a frusto-conical shape and defining a chambe...

Abstract

The invention discloses a connecting device for connecting structural elements, in particular ribs, mesh structures and the like, said connecting device comprising: at least a first shell (4; 44; 403; 411), the first housing has a cavity (14; 414; 144) and can be connected with the first structural element (2; 20; 200; 121); at least one connecting body (5; 56; 511 ), said connector has at least one insertion portion (119; 58; 591) for insertion into said cavity (14; 414) of said first housing (4; 44; 403; 411) ; 144) and can be associated with the second structural element (3; 30; 131); and locking means (11, 12, 13, 15, 17; 60, 61, 62, 63, 47; 621, 623, 653), said Locking means are used to lock said insertion portion (119; 58; 591) of said connecting body (5; 56; 511) inside said cavity (14; 414; 144). The housing can be arranged in the cup-shaped element and can be connected to the connecting body in a swivel / hinge manner.

Description

technical field [0001] The invention relates to a connecting device for connecting structural elements, in particular elements such as ribs and mesh structures. The invention also relates to a rib for supporting and reinforcing a tunnel, said rib comprising connecting means for connecting said structural elements, and to a method for installing a supporting rib in a tunnel. Background technique [0002] In the field of support structures it is known to use structural elements connected to each other to produce the final form of said support structure. These structural elements may have open sections (eg C or double T sections) or closed sections. In the case of a closed section, the structural element is tubular and may have any form of section, for example circular, square, rectangular or triangular. [0003] For supporting tunnels, such as motorway tunnels or railway tunnels, it is known to use reinforcing arches called "ribs". In particular, ribs generally comprise a p...
